Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in gitweb allow for remote execution of |
| 19 |
arbitrary commands. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
GIT - the stupid content tracker, the revision control system used by |
| 25 |
the Linux kernel team. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-util/git < 1.6.0.6 >= 1.6.0.6 |

|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been reported in gitweb that is part of |
| 39 |
the git package: |
| 40 |
|
| 41 |
* Shell metacharacters related to git_search are not properly |
| 42 |
sanitized (CVE-2008-5516). |
| 43 |
|
| 44 |
* Shell metacharacters related to git_snapshot and git_object are not |
| 45 |
properly sanitized (CVE-2008-5517). |
| 46 |
|
| 47 |
* The diff.external configuration variable as set in a repository can |
| 48 |
be executed by gitweb (CVE-2008-5916). |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A remote unauthenticated attacker can execute arbitrary commands via |
| 54 |
shell metacharacters in a query, remote attackers with write access to |
| 55 |
a git repository configuration can execute arbitrary commands with the |
| 56 |
privileges of the user running gitweb by modifying the diff.external |
| 57 |
configuration variable in the repository and sending a crafted query to |
| 58 |
gitweb. |
| 59 |
|
| 60 |
Workaround |
| 61 |
========== |
| 62 |
|
| 63 |
There is no known workaround at this time. |
| 64 |
|
| 65 |
Resolution |
| 66 |
========== |
| 67 |
|
| 68 |
All git users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=dev-util/git-1.6.0.6" |
| 72 |
